Search – disable searching by author xyz

With core search if you search for say ‘bill’. The results include all nodes with the keyword bill but also all the nodes where the author (user) is bill. On our site we don’t display the author name on any page. So this is a bit misleading to the site visitor.

We are using Drupal 8, is it possible to disable core search from indexing the author or exclude these from the results all together.
